Battle of San Rigoberto de Amazonas

The Battle of San Rigoberto de Amazonas occurred in 1648 during the Portuguese Restoration War. The conflict began when Spain attempted to establish a colony in the Amazonas region of South America, where Portugal had already founded several colonies. The Portuguese allied with the Zapotec and Tupi tribes on the south bank of the river, where they had established their settlement of Banco do Sul, and they shipped their army across the Amazon River to the north bank. The Spanish explorer Cristobal de Inciso was killed when he headed to investigate the landing, and the Portuguese forces moved on the undeveloped Spanish town and burnt down the town center, forcing the Spanish to surrender. This battle was one of the many clashes between the Portuguese and Spanish forces in the Amazonas region.
